檢查並在陣列中改變的值

Question

我有存儲在會話

我循環通過所述數據，以便多陣列，以改變被設置爲「1」的值，並將其設置爲「0」

但由於某種原因，即使它找到了價值，它也不會改變它。

這是我有：

Array (
    [0] => 1 
    [1] => 0 
    [2] => admin_user 
    [8] => 1 
    [3] => 2 
    [4] => Array (
     [7] => Array ( 
      [0] => User1 
      [1] => 1 
      [2] => 1 
      [3] => w.jpg 
      [4] => 1 
      [5] => 1 
      [6] => 500 
      [7] => 50 
      [8] => 3000 
     ) 
     [1] => Array ( 
      [0] => User2 
      [1] => 1 
      [2] => 3 
      [3] => d.jpg 
      [4] => 1 
      [5] => 0 
      [6] => 200 
      [7] => 85 
      [8] => 5000 
     ) 
    ) 
) 

所以在PHP我想在位置4.

改變位置5陣列中的值這是我做到了：

foreach($_SESSION['player_data'][4] as $key){ 
    if($key[5] == 1){ 
     $_SESSION['player_data'][4][$key][5] = 0; 
     break; 
    } 
} 

但它不會將其設置爲0，則保持爲1的煩人:(我要去哪裏錯了？

查nge到：

foreach($_SESSION['player_data'][4] as $key => $value){  
    if($value[5] == 1){ 
     $_SESSION['player_data'][4][$key][5] = 0; 
     break; 
    } 
}
